Abstract

Biochar contains a limited quantity of available mineral nutrients, requiring its addition in large quantities, in temperate soils, and in association with nitrogen (N) fertilizer and/or manure. Alternatively, biochar could be pre-conditioned with urea ammonium nitrate (UAN-enriched biochar), requiring lower inputs of biochar. The objective of this study was to evaluate the long-term (150 years) impact of the addition of UAN-enriched biochar on soil organic carbon (SOC), and soil active, slow and passive carbon (C) fractions compared to other commonly used agroecosystem management practices in a coarse and medium textured soil using the Century Soil Organic Matter Model.
